Inksky
A frozen e-reader screen is alarming — especially if you’re mid-flight and your only book is trapped on a device showing the same static page. the practical takeaway: most freezes are software-level and fixable with a simple hard reset. The better news: e-ink screens don’t require power to maintain an image, so even when the device crashes, the screen may look “on” when it isn’t.
Frozen screen vs. broken screen: how to tell
Before you do anything, identify which problem you have. A frozen device shows a perfect, coherent image — book text, the home screen, a screensaver — just stuck. A broken screen shows lines, cracks, dead zones, or a spiderweb pattern that doesn’t change. If the latter, skip the resets; your screen substrate is physically damaged and needs replacement. You can confirm by plugging the device in and listening for connection sounds on your computer — a broken-screen device may still be recognised over USB, confirming the mainboard is alive.
Brand-specific hard reset instructions
Kindle (all models)
Hold the power button for 40 seconds. Do not just hold it for 10 or 20 — 40 full seconds, even if the screen flashes or the LED blinks midway. The device will reboot and show the Kindle logo. For older models with a removable back (Kindle Keyboard, Kindle DX), a 20-second hold typically suffices. If the screen stays frozen after two attempts, plug it into a charger for at least 30 minutes (a deeply drained battery can mimic a freeze) and try again.
Kobo (Clara, Libra, Sage, Elipsa, Nia)
Hold power + one of the physical page-turn buttons simultaneously for 15–20 seconds until the screen flashes and the Kobo logo appears. For the Kobo Nia (which lacks page-turn buttons), hold the power button alone for 20 seconds. If the device repeatedly freezes on a specific book, the book file may be corrupt — connect to a computer and delete the offending EPUB/KEPUB from the device’s storage, then reboot.
Boox (all Android-based models)
Hold the power button for 20 seconds until the screen cuts to black and the Boox logo appears. If the device is completely unresponsive, try holding power + volume down for 15 seconds to enter recovery mode, then use the volume keys to select “Reboot system now” and press power to confirm. Boox devices running older firmware occasionally freeze during Wi-Fi transfers of large PDFs — updating to the latest firmware (Settings → Firmware Update) reduces this.
reMarkable (1, 2, and Paper Pro)
Hold the power button for 15 seconds. Release when the screen goes fully blank, then press the power button again to turn it back on. If that doesn’t work, hold power for 10 seconds, release, then immediately hold it again for 5 seconds. The reMarkable Paper Pro uses a slightly different boot chain — if your device repeatedly freezes after the 3.16 update (rare), try a factory reset via Settings → General → Reset.
PocketBook (all models)
Hold the power button + the bottom hardware button (the one below the D-pad or the menu/home button, depending on model) for 15 seconds. The device will reboot. For the PocketBook Era and Era Color, holding just the power button for 20 seconds also works.
Still frozen? Try these before contacting support
- Charge it fully — connect to a 5W/1A charger (not a fast charger) for at least 2 hours. E-readers negotiate poorly with USB-C PD chargers and may not draw enough current to wake from a deep-discharge state.
- Try a different cable and charger — a bad cable can prevent charging without any obvious sign.
- Temperature — if the device was left in a hot car or freezing cold, bring it to room temperature for an hour before attempting a reset. E-ink panels and lithium batteries both misbehave at extremes.
- Last resort — discharge completely — leave the device unplugged for 2–3 weeks until the battery drains entirely, then charge it. This forces a cold boot and often clears persistent software hangs.
When to contact support
If none of the above works, you’re likely dealing with a hardware failure — a dead battery, a failed e-ink controller, or a damaged mainboard. For Kindles still under the 1-year warranty, Amazon support will usually offer a replacement or refurbished discount. Boox users should contact the reseller (Boox devices have limited direct warranty outside China). reMarkable offers a 100-day return window and 1-year warranty. PocketBook has regional support through their distributor network — check your purchase receipt for the local contact.
